4-Chloro-1-naphthol is a commonly used substrate for horseradish peroxidase (HRP). HRP catalyzes oxidation of 4-chloro-1-naphthol in the presence of peroxide to the blue insoluble product 4-chloro-1-naphthon. It is used for both blotting and immunohistochemical staining but is less sensitive than other precipitating HRP substrates.
